A study on development of a reduced-order distillation model and identification using nonlinear filtering techniques

증류공정의 차수감소모델 개발 및 비선형휠터기법을 이용한 모델인식에 관한 연구

A linear form of reduced-order distillation model is proposed, which contains the physical properties of distillation process and can be used in real time applications. The proposed model is linear in terms of liquid mole fraction and contains some tuning parameters. To verify the applicability of the proposed model, the model identification using nonlinear filtering techniques was applied. As a result, it was found that this model represented the simulated distillation process very closely as the parameters were converged.
